I chose the inrad version based on the better isolation figures in the QST 
review. Also the
Inrad uses toroidal rather than the dunestar's air wound coils which I liked 
better. (I had
tried a home brew version with air wound coils and found it difficult to 
eliminate coupling
enough to allow stable tuning. The dune star has this figured out no doubt but 
I figured it
was one less thing).

I run 100 watt rtty with no issues.  It is also somewhat easy to repair 
(haven't had to retune) 
when you forget and put a kw through it. 

I do believe you need better bandpass filters than the ICE 419 variety to be 
safe. (I ended up
adding coaxial stubs to help it in my set up).
